Description

3

NC

Not Connect.

4

Vin

Supply Voltage Input Pin.FAC1513 operates from a 1.0V to 20V DC voltage.

Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.

5,6

SW

Power Switch Output Pin. SW is the switch node that supplies power to the

output.

7,8

GND

Ground Pin. Care must be taken in layout. This pin should be placed outside of

the Schottky Diode to output capacitor ground path to prevent switching current

spikes from inducing voltage noise into FAC1513.

1

FB

Feedback Pin. Through an external resistor divider network, FB senses the

output voltage and regulates it. The feedback threshold voltage is 0.8V.

2

EN

Enable Pin. EN is a digital input that turns the regulator on or off .Drive EN pin

high to turn on the regulator, drive it low to turn it off.
